In basic computer, document file management system 100 according to the present invention carries out work.Document file management system 100 also comprises the distinctive filter information history management/edit cell 41 of the present invention except that original document management unit.When only closing heart function, all the other constituent components are divided into: application program 46, and it creates the document by document file management system 100 management; Graphics Device Interface (below be referred to as GDI) 47, it is as the part of basic OS; Printer driver 200; And print spooler (spooler) 48, the data that its interim storage is generated by printer driver 200.
Notice that the title of these assemblies and functional framework change a little to some extent according to basic OS, but title and functional framework not essential for the present invention, need only the technical functionality of module in can realizing inventing.Module title for example GDI or printer driver is Windows
OS is distinctive, and the identical function in another basic OS is realized by the module that is called as graphics core etc.Print spooler 48 also can be realized by processing is enrolled in the module that is called as print queue.Usually by the software that is called as basic software (BIOS) hardware for example the CPU1 shown in Fig. 1, RAM2, ROM3 and 11 times control of hard disk have the basic computer 1000 of these constituent components, and application software moves under this basic software.Printer driver 200 also is considered to a kind of Application Software Program.Application program 46 is meant the application software (for example, Word or electrical form software) that operates on the basic software.In addition, a plurality of application programs 46 can start (application program 46 mainly changes according to memory capacity) at arbitrary timing.
By the situation that is used as application program 46 with the arbitrary image software for editing is that example illustrates common printing.Application program 46 is operated main carries out image editing according to the user.The image that generates in order to print, the user utilizes selection such as mouse to be presented at print menu on the CRT10, and carries out and print.In first embodiment, will be called document data or document data file by the data that application program 46 generates, and no matter the content of data how.
GDI47 is from printer driver 200 reception information, for example rendering performance or the print resolution of printing device (being printer 3000 in this example), and wherein these printer driver 200 management depend on the information of each printing equipment model.GDI47 handles API (application programming interfaces) function that application program 46 is called.According to the content of handling, printer driver calls the function that offers GDI47.This function is predetermined interface (device drives interface: be commonly called DDI).The founder of program of printer driver creates and is mainly used in data-switching data are outputed to the printer driver of actual printing equipment from this interface.
In first embodiment, print data generation unit 42 keeps (for example for example handling layout processing when carrying out in printer driver 200, Nin1) and Flame Image Process (for example, affix one's seal or halftone process) time employed driver filtrator 43, with reference to the graphics processing unit in the printer 3,000 51 these processing are illustrated above.Use driver filtrator 43 according to specifying.More specifically, print data is through necessity processing of driver filtrator 43 and the processing of the Device Filters 52 in the printer 3000, to generate final output image.By suitable use driver filtrator and Device Filters, can realize considering the print system that the load of the performance of the performance of basic computer 2000 and printer 3000 is shared.
Share with reference to figure 3 and 4 pairs of loads and to be described in detail by suitable use filtrator.As filter type, the layout of Fig. 3 illustration 4in1, the secret seal of Fig. 4 illustration.
The printing of 4 page datas in the 4in1 layout of the document file management system request among Fig. 3 shown in 401.Upper part shows the processing sequence 301 of carrying out actual 4in1 by driver filtrator 402.The information that the print data handled through 4in1 and expression 4in1 have been finished " is finished 4in1 " and is write spool file 403.By this spool file 403 being transferred to printer controller 4000 with path 31 that principal computer 1000 is connected with printer 3000.Because 4in1 finishes, so printer controller 4000 will be exported result's 405 outputs.Printer driver is based on generating print data by GDI from the document data that application program receives, and describes this print data by PDL.PDL describes the position and the size of object in each page etc.Therefore, when the driver filtrator was carried out 4in1 and handled, four pages data that generated by application program were mapped in one page, and generate/four pages position and size is described in 1 page of print data after automatic spool is handled.
Lower part shows the processing sequence 302 of not carrying out 4in1 by driver filtrator 402.The information that indicating equipment is carried out 4in1 " is carried out 4in1 " and is write spool file 407.Similar with above example, by path 31 transmission spool files, and spool file is exported will export result 408 through the 4in1 processing of Device Filters 404.When with PD L being example when describing, by the print data that printer driver generates and automatic spool is handled comprise by describing four pages of acquisitions that application program generates by PD L data and on one page four pages of required parameters of arrangement.Dwindle and reset this 4 page data by Device Filters to create and to export for example data bitmap of 4in1.
Because driver filtrator 402 is almost carried out identical processing with Device Filters 404, therefore handle and between principal computer 1000 and printer 3000, to share load by which execution in judgement driver filtrator 402 and the Device Filters 404.
Fig. 4 illustrates and the similar flow process of the flow process of Fig. 3.Fig. 4 illustrates secret seal rather than 4in1 layout.About affixing one's seal, realize that identical load shares.In Fig. 4, in the part 412 document data and the seal image of accepting to affix one's seal transmitted simultaneously as spool file below.In fact, seal image can be stored in the storage box 55 of printer 3000.In this case, by using Device Filters, seal image does not need to be delivered to printer from computing machine.
Shown in Fig. 3 and 4, filtrator is to carry out the software module handle layout for example or to affix one's seal.Filtrator as software module has very high extensibility and very high dirigibility.Also the filtrator with the function except that function shown in Fig. 3 and 4 can be installed in printer driver or the printer.In this case, can specify institute's installed filters to print once more to carry out.

The storage of filter information and reproduction
Operation to document file management system 100, printer driver 200 and printer controller 4000 describes with reference to the accompanying drawings.
Document file management system
Fig. 6 A and 6B are the process flow diagrams that the operation of document file management system (program) 100 is shown.Fig. 6 B illustrates the processing sequence of the document file management system 100 till printing inputs to the document data of hot folder.Document file management system 100 is periodically monitored hot folder.When document data is inputed to hot folder, when promptly being stored in the hot folder, document file management system 100 is opened the document file (step 6A) by using the application program of having created document files.Document file management system 100 reads the print setting information relevant with this hot folder, and (step 6B) stored in its setting of printing as document data to be printed.Document file management system 100 judges whether the filter information relevant with this hot folder exists (step 6C).If relevant filter information exists, then document file management system 100 can be stored this filter information with discerning, as the filter information (step 6D) of the employed filtrator of print processing of specifying the document data.Afterwards, flow process is transferred to Fig. 6 A.Notice that filter information not only comprises the information that is used to specify filter module, also comprise the information of expression filter process order.This is because when the filter process in execution graph 3 and 4, the output result changes according to the order of application program.If the at first processing in the execution graph 3 is then at the synthetic secret seal of the central authorities of the one page with 4in1 layout.If the at first processing in the execution graph 4, four pages that then will synthesize secret seal in every page central authorities convert 4in1 to.
For the document data of printing stored in hot folder, follow the processing among the execution graph 6A after the processing in Fig. 6 B.For the processing of the print processing of not using hot folder in also can execution graph 6A.
In Fig. 6 A, employed filter information during document file management system 100 judges whether to have specified clearly and prints promptly, judges whether the filter information that can store exists (step 61) with discerning in the step 6D of Fig. 6 B.If specified the filter information of using clearly, then document file management system 100 specifies this filter information as the filter information that is used to specify the filter module of use, and carries out and print (step 66).Can realize this appointment by for example filter information being passed to printer driver via operating system.For example, by operating system will be to be printed document data pass to printer driver with the information of specifying specified filter information.
If document file management system 100 is not instructed to any filter information, then it has judged whether to ask the storage (step 62) of filtrator history.Document file management system 100 can be pointed out the user storage of the filtrator history in judging whether to ask to print.Alternatively, often whether document file management system 100 can historical the setting as system of storage keep.When by user's appointment or system the storage of request history being set, document file management system 100 is specified about the automatic spool of the filter information of employed filter module and is handled, and (step 65) printed in execution.For this purpose, document file management system 100 special command (order of filtrator historical collection) that will be used for the de-entrainment filter information history passes to printer driver with document data.
If there is not the collection of request filter information history, then document file management system 100 is carried out the normal printing (step 63) of printer driver.In this case, document file management system 100 can suitably be determined filter information and it is passed to printer driver.In this case, carry out following the processing.Document file management system has the tabulation of operable Device Filters module of printer and the operable driver filter module of driver.Can when for example printer driver being installed, store this list information.In order to realize specified setting of printing, from obtainable filter module, determine the filtrator that uses.Provide identical result to driver and equipment () filter module for example, the result shown in Fig. 3 or 4, then filter process is loaded between principal computer and printer and shared if can in the filtrator of determining to be used, use.By the handling property of computing machine, the handling property of printer and the load of filter process are set up index (indexing), load and share.First embodiment does not relate to how sharing load.If the result who shares as load determines the Device Filters module and the driver filter module that use, then document file management system 100 filter information that will be used to specify these modules passes to printer driver with document data to be printed.
Printer driver
Fig. 7 is the process flow diagram that the operation of printer driver 200 is shown.In print processing, printer driver 200 confirms whether document file management system 100 has indicated the filter information of using to it, and promptly whether printer driver 200 has received about treating the filter information (step 71) of document printing data.As mentioned above, when document file management system 100 always passed to printer driver 200 with filter information, this result of determination is "Yes" always.If printer driver 200 has been instructed to filter information, then printer driver 200 uses driver filter module specified in the driver filter information 43 of being managed to carry out filter process (step 76).According to handling with the corresponding order of the appointment of filter process order.
If printer driver 200 is not instructed to any filter information, then judge whether to indicate it that filter information is carried out automatic spool and handle, promptly whether the order when pre-treatment is filtrator historical collection order (step 72).If order is the order of filtrator historical collection, promptly indicating 200 pairs of filter information of printer driver to carry out automatic spool handles, then printer driver 200 adds the driver filter information that is used to specify employed Device Filters to print data, and this driver filter information is carried out automatic spool handle (step 75).Handle if also indicate 200 pairs of filter information of printer driver to carry out automatic spool, then printer driver 200 is carried out normal process, and under the situation of not adding any filter information print data is carried out automatic spool and handle (step 73).Execution is called as the program of separating spooler (despooler) and is transferred to printer 3000 with the print data after automatic spool is handled as print job.
When using filter module, also can share the load of filter process by printer driver according to setting of printing.In this case, in step 73, carry out above-mentioned load and share processing, and the filter information of being judged is appended to print data.
Printer controller
Fig. 8 is the process flow diagram that the operation of printer controller 4000 is shown.Printer controller 4000 judges whether institute's information transmitted is print job (step 81).If institute's information transmitted is not print job, then printer controller 4000 judges whether institute's information transmitted is the filter information history request of obtaining (step 89).Filter information history is obtained request and is sent from for example document file management system 100, but is not print request, can arrive printer 3000 by the path different with the path of print command.Even identical with the path of print command, filter information history obtain request under without any situation about handling by transmission such as printer drivers.No matter path how, the request of obtaining of filter information history arrives printer 3000.
If judge that in step 89 institute's information transmitted is not the request of obtaining, then printer controller 4000 is carried out and the corresponding processing of request (step 92) that receives.If institute's information transmitted is the request of obtaining, then printer controller 4000 obtains filter information history (step 90) from storage box 55, and the filter information history of obtaining is sent it back basic computer (step 91).If judge that in step 81 institute's information transmitted is print job, then printer controller 4000 judges whether to have indicated the filter information of using (step 82) to it.If printer controller 4000 has been instructed to the filter information of using (that is, embedding Device Filters information in print data), then printer controller 4000 prints, and makes to reproduce filter information (step 88) based on specified filter information.More specifically, printer controller 4000 uses based on the filter module of this filter information appointment and carries out filter process.Printer controller 4000 is carried out print processing based on the data bitmap that is obtained.If the version by the filter module of filter information appointment is older than current obtainable version, then printer controller 4000 is transferred to the server unit (not shown) with filter information, and receives corresponding filter module.Printer controller 4000 is installed the filter module that receives therein, makes to carry out this filter module.Printer controller 4000 uses this filter module to carry out filter process.After processing finished, the filter module of the redaction after printer controller 4000 will be replaced returned to upstate.For this purpose, can preserve the filter module of redaction, or from above-mentioned server unit, download and it is installed in the printer controller.
If judge the filter information of not indicating printer controller 4000 any uses in step 82, then printer controller 4000 confirms whether to ask its stored filter device information history (step 83).If request printer controller 4000 stored filter device information history, then printer controller 4000 prints, and storage simultaneously is used to specify the Device Filters information (step 86) of employed Device Filters.The reason of printing in the memory device filter information is in order to detect when reproducing the required parameter of filter process each, this parameter to be stored as the part of filter information.In addition, printer controller 4000 filter information that will be used to specify employed driver filtrator and Device Filters is stored in the storage box 55 (step 87) as filter information history.Even when not using filtrator, still storage representation does not use the information of filtrator.Form with reference to 9 pairs of filter information history of figure describes.If do not ask printer controller 4000 stored filter device information history in step 83, then flow process is transferred to normal printing, and printer controller 4000 is carried out normal the printing and do not stored any history (step 84).
Fig. 9 illustrates filter information history 201.By filter information history management unit 54 managing and filtering device information history 201 in storage box 55.Filter information history 201 is made up of the history of printing ID, the user name that is used to specify the user who carries out printing, date printed and the time that are used as identifier, printer setup information, employed driver filter information, employed Device Filters information, filtrator use order information etc.Selection also is provided for from the required information of the document file management system request of obtaining.For example, have the filter information history of the user name identical,, then will send it back principal computer with the corresponding filter information history of this date and time if perhaps obtain appointed day and time in the request at this with sending the user name of obtaining requesting users.In case receive the filtrator historical information, then the document file management system 100 of principal computer is associated with storing the filtrator historical information with hot folder.Printer controller can be deleted the filter information history of being obtained by document file management system 100 or continue to store it.In the latter case, through the schedule time or by using clear and definite delete command from document file management system 100 as trigger, deletion filter information history from storage box 55.
Figure 11 illustrates the sequence of document file management system 100 when obtaining filter information history.Document file management system 100 sends the filter information history request of obtaining (step 1101) to printer controller 4000.Document file management system 100 receives this request responding from printer controller 4000, and is associated with storing the filter information (step 1102) that is included in the filter information history that receives with hot folder.As a result, finish related between the setting of printing of hot folder and the appointment of the filter module that comprises use.
The editor of setting of printing
Figure 10 A simply is illustrated in the dialog box that hot folder can be set in the document file management system 100.Especially, the editor to filter information describes.Document file management system 100 is by filter information history management/edit cell 41 managing and filtering device information history.Simultaneously, document file management system 100 management can be illustrated it above by a pair of driver filtrator 43 and the Device Filters 52 of printer driver 200 and printer 3000 uses.Various obtainable driver filtrators and Device Filters are used as icon display on user interface.And the filtrator (filtrator of use) that use obtainable and the obtainable but combination of obsolete filtrator (obsolete filtrator) according to the icon operation change on the user interface.Also target printer can be changed over another printer, and can manage with the corresponding obtainable filtrator of printer present and with conflicting that the user is provided with.
For example, when the operator opened user interface among Figure 10 A, shown in Figure 10 A, at this moment filtrator of Shi Yonging and obsolete filtrator were used as icon display in window 101 and 102.The operator selects these icons and clicks " interpolation " or " deletion " button, or carries out drag and drop.Then, the expression " use " or " not using " information be recorded in corresponding each filter information of each icon in.In the step 6C of Fig. 6 B, the having/do not have of the filter information that the filter information judgement of the information that is used for record expression " uses " is associated.
By said structure and processing sequence, will specify the filter information of employed filtrator to store according to setting of printing as filter information history according to the print system of first embodiment.When request uses this setting to print, specify the filtrator that uses, and use specified filtrator to carry out filter process.Therefore, can reproduce the content of exporting printed material once by printing again subsequently.
Owing to can edit the filter information relevant, therefore can easily change some filtrator based on the setting of printing in past with hot folder.
